What could cause two flat tires in quick succession after getting new tires. It does not appear to be bad luck.

I replaced all 4 tires on Friday morning.

  • On Friday afternoon (same day!), I had a flat tire in my rear passenger side. I was driving on the highway and car started to get shaky. I then pulled over and noticed it was flat (10 psi).
  • Really upset, I took it back to a different branch of the same company (Caliber). They replaced the tire.
  • I didn't drive for two days. Two days later, I drove on the highway and it was another flat tire in the same place (rear passenger side).

Replaced by two different places (though same company), yet I still got a flat in the same place. Any ideas?

They found the issue. related to corrosion in the valve stem. They didn't replace it when they replaced the tires. Awful service, I'm never going back there.

Found a related question/answer here.

Flat tire right after replacing all tires - what could be the cause?

whoever changed the tires didn't use new valve stems and/or valves. They're located in the rim of the wheel, so it's entirely possible that they were overlooked They can become brittle and crack with age, just like tires, and should be replaced at every tire change. The valve could also be leaking, especially if it doesn't have a protective cap and has been exposed to the elements.
